DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for cleaning roads, side walls in tunnels, and lighting.

[0002]

2. Description of the Related Art Conventionally, in order to wash a side wall in a tunnel, a large-sized rotating brush similar to that used in a car washing or the like is equipped on a side of a special washing car, and the rotating brush is sprayed with detergent and water. The side walls of the tunnel were rubbed with a brush to remove fouling substances.

[0003]

As described above, in the conventional washing car, since the side wall in the tunnel is rubbed by the rotating brush, when the decorative board is washed, a fine scratch is formed on the decorative board. There was a risk of attaching.

[0004] In addition, the traveling speed of the washing car during the washing needs to be extremely low (1 km / h). However, the fact that the traveling speed of the washing car is low means that the washing car stays in the tunnel. Since the time is longer, the working time is longer, the cleaning cost is higher, and the traffic of general vehicles is restricted for at least one lane for a longer time, which may cause traffic congestion and accidents.

Furthermore, since the rotating brush is used, even if the cover is used, the cleaning liquid and the liquid containing the contaminants are scattered in the form of a mist by centrifugal force and adhere to a general vehicle traveling on the side. , Discomfort to the passengers of the general vehicle,
In some cases that can cause accidents.

The exposed surface of the concrete has irregularities, but with a rotating brush, it is difficult for the wire of the brush to reach the bottom of the concave portion, so that cleaning cannot be performed reliably.

Furthermore, in the conventional apparatus, the structure is complicated due to the use of the rotating brush, and it is necessary to develop a dedicated vehicle. Therefore, the price is inevitably increased.

SUMMARY OF THE INVENTION The present invention solves the problems of the prior art at once, and aims at realizing an inexpensive, highly efficient and highly safe cleaning method and apparatus without using a rotating brush. .

FIGS. 7 and 9 show only the outline.

The watering truck is equipped with a water tank 17 containing 10,000 liters of water and a detergent tank 18 containing 300 liters of liquid detergent, and also has a pump (not shown). .

In the vicinity of the rear end of the watering vehicle in the traveling direction, a vertical support 20 as shown in FIG. 9 is mounted so as to be movable in the left-right direction, and the base end of the horizontal arm 21 is attached to the vertical support 20.

However, two means for cleaning the upper side wall can also be mounted on the upper left and right sides of the watering vehicle.

FIG. 9 shows a state in which the left side wall is cleaned with high-pressure water. When the right upper side wall is cleaned with high-pressure water, first, the vertical support 20 is moved rightward. Then, when the horizontal arm 21 is turned rightward, the high-pressure injection nozzles 4 and 5 are opposed to the right upper side wall, and the right upper side wall can be washed with high-pressure water. .

A walking passage 22 is formed in a step shape on the side wall in the tunnel.

In the case of a relatively flat side wall such as the right side wall, the decorative panel 10 can be easily washed as it is. However, in the case where the walking passage 22 is formed in a stepped shape as in the left side wall,
In order to wash the decorative plate 10 on the upper side wall, the means for cleaning the upper side wall needs to be close to the inner wall of the tunnel as shown in FIG.

Since the handrail 23 is provided at the edge of the walking passage 22, to move the means for cleaning the upper side wall closer to the inner wall of the tunnel, first move the vertical support 20 to the left. Then, the substrate 1 is swung vertically around the horizontal arm 21 so as to be in a horizontal state, is passed over the handrail 23 to the left, and then the substrate 1 is again moved to the horizontal arm 2.
By pivoting vertically around 2 and returning to a vertical state, it is possible to clean the upper side wall as shown in FIG.

The decorative board 1 on the lower side wall of the walking passage 22
In the case where 0 is washed, the washing can be performed as it is by the washing means mounted on the lower side of the watering vehicle.

Further, in the above embodiment, the side wall of the tunnel is cleaned. However, by changing the form of the cleaning device, the lighting equipment 24 in the tunnel can be cleaned. It is also possible to clean the portion to be cleaned.
